The Problem

AI agents are black boxes. You call an API, you get a response, but you have no visibility into:

  • What did the agent decide to do? Where are the reasoning steps and decision points?
  • Which tools did it call? In what order? What were the inputs, outputs, and execution times?
  • How much did it cost? Token counts, API costs, hidden charges, cost per operation?
  • Did something go wrong? How did the agent handle errors? Did it recover automatically?
  • Is it actually thinking like I expected? Or is it making unexpected choices or inefficient decisions?
  • How can I debug issues? Without observability, troubleshooting agent behavior is nearly impossible.

This lack of observability makes debugging, monitoring, optimizing, and improving agents incredibly difficult. You're essentially flying blind when it comes to understanding what your agent is actually doing.


The Solution

AgentLens is a comprehensive, production-ready TypeScript library that automatically logs every step of your agent's execution in a structured, queryable, privacy-preserving format. It provides complete visibility into agent behavior with zero configuration required.

Unlike basic logging solutions, AgentLens captures rich context about every LLM call, tool invocation, reasoning step, and error. It structures this data according to the ARLS schema (AI-Readable Log Schema), making logs queryable by both humans and AI tools. The library is designed to be completely transparent — requiring no changes to your existing agent code except for a single wrap() call.

Key Design Principles

Zero Runtime Dependencies — The core package has zero production dependencies, making it lightweight and dependency-free.

Privacy-First Architecture — PII (Personally Identifiable Information) is detected and redacted before any log is written, with multiple redaction strategies (MASK, HASH, DROP, PLACEHOLDER).

Async Non-Blocking — All transport writes happen asynchronously via internal queues, ensuring logging never blocks your agent's execution.

Type-Safe by Default — Built with TypeScript strict mode enabled. All events conform to a versioned JSON schema with zero any types.

Multiple Output Modes — Choose between beautiful human-readable terminal output with ANSI colors and emoji, or machine-readable JSONL format optimized for AI tools like Claude Code.

SDK-Agnostic — Works seamlessly with Anthropic SDK, OpenAI SDK, or any async function as a tool. Add a single line of code and get full observability.

Key Features

Automatic LLM Logging — Anthropic, OpenAI SDKs patched transparently with zero code changes ✅ Tool Call Tracing — Input/output/duration/status for every tool invocation ✅ Cost Tracking — Automatic token counting and cost calculation for all major LLM models ✅ Privacy-First — PII detection and redaction before any log is persisted (6 detector types) ✅ Multiple Output Modes — Beautiful human-readable terminal output + JSON for AI tools ✅ Zero Config — Works out of the box with your existing SDK, no configuration needed ✅ Typed Events — ARLS schema ensures all logs are structured and queryable ✅ Async Non-Blocking — Transport writes never block your agent or slow it down ✅ Log Rotation — File transport automatically rotates logs at configurable size limits ✅ Context Propagation — Automatic run_id, trace_id, and step_index tracking across async boundaries ✅ CLI Tools — Command-line utilities for analyzing runs, tracing execution, and computing statistics ✅ Open Format — ARLS schema is versioned and documented, making logs consumable by external tools


What We're Trying to Achieve

AgentLens aims to solve a critical gap in AI agent development: the complete lack of observability into agent behavior. While existing solutions offer partial visibility, AgentLens provides complete, structured, queryable logs of every step an agent takes.

The Gap in Existing Solutions

Most existing observability tools fall into one of these categories:

  1. LLM-Specific Logging (LangSmith, Datadog LLM)

    • ❌ Only track LLM calls, not tools
    • ❌ Limited to a single vendor's ecosystem
    • ❌ Closed format not readable by AI tools
    • ✅ Good cost tracking
  2. General Application Logging (standard logging, Datadog APM)

    • ❌ Not designed for agents
    • ❌ No understanding of agent phases or reasoning
    • ❌ No automatic cost calculation
    • ✅ Works with any system
  3. Agent Framework Built-ins (LangChain callbacks, LlamaIndex)

    • ❌ Tied to a specific framework
    • ❌ Only work if you use that framework
    • ❌ Inconsistent schema across frameworks
    • ✅ Easy to integrate if you use the framework

What AgentLens Does Differently

Agentlens is framework-agnostic and SDK-agnostic observability designed specifically for agents.

Why Agentlens is Better

1. Framework & SDK Agnostic

  • Works with Anthropic SDK, OpenAI SDK, or any custom tools
  • Not tied to LangChain, LlamaIndex, or any framework
  • Add observability to existing agent code in 1 line
  • Easy to integrate with internal tools and custom agents

2. Designed Specifically for Agents

  • Understands agent phases (PLAN, TOOL_CALL, OBSERVE, REFLECT, RESPOND)
  • Captures reasoning steps and decision points
  • Tracks complete execution context across async boundaries
  • Queries logs for agent-specific insights

3. Privacy-First by Design

  • Detects and redacts 6 types of PII before logging
  • Multiple redaction strategies (MASK, HASH, DROP, PLACEHOLDER)
  • PII redaction happens automatically, requires no configuration
  • Logs are safe to send to external services

4. AI Tool Friendly

  • ARLS schema is open and documented
  • Output can be parsed by Claude Code, Copilot, and other AI tools
  • AI debug hints help tools understand what happened
  • Machine-readable format designed for LLM analysis

5. Zero Overhead

  • Core package has zero runtime dependencies
  • Async non-blocking transport queues
  • Logging never blocks agent execution
  • Lightweight enough to run in production

6. Beautiful Developer Experience

  • Colored terminal output with emoji
  • Human-readable event summaries
  • CLI tools for run analysis (trace, analyze)
  • Clear cost breakdown per operation

Quick Start

1. Installation

TypeScript / Node.js

Minimal setup:

npm install @agentlens/core

Full SDK support:

npm install @agentlens/core @agentlens/transport @agentlens/interceptors
npm install @anthropic-ai/sdk  # For Anthropic
# OR
npm install openai              # For OpenAI

All packages: Visit npm @agentlens

Python 3.11+

Minimal setup:

Full installation:

pip install agentlens

All packages: Visit PyPI agentlens search

2. Initialize AgentLens

import { AgentLens } from '@agentlens/core'
import Anthropic from '@anthropic-ai/sdk'

const lens = new AgentLens({
  agent: 'MyResearchBot',
  mode: 'human',
  transport: 'console',
})

const client = lens.wrap(new Anthropic())

3. Use Your SDK as Normal

const response = await client.messages.create({
  model: 'claude-3-5-sonnet-20241022',
  max_tokens: 1024,
  messages: [{
    role: 'user',
    content: 'Research: What are the top AI observability frameworks in 2025?'
  }],
})

console.log(response.content[0].text)

4. Close the Logger

await lens.close()

What You'll See

In human mode, the output looks like this:

In ai mode, every event is output as JSONL with AI-friendly context:

{"agentlens_version":"1.0","schema_type":"LLM_CALL","timestamp":"2025-04-04T12:34:56.789Z",...}
{"agentlens_version":"1.0","schema_type":"TOOL_CALL","timestamp":"2025-04-04T12:34:57.123Z",...}

How It Works

Architecture Overview

AgentLens is built as a monorepo with 6 specialized packages:

  • @agentlens/core — ARLS schema definitions, event builders, main AgentLens class
  • @agentlens/interceptors — SDK wrappers for Anthropic, OpenAI, and custom tools
  • @agentlens/privacy — PII detection and redaction engine
  • @agentlens/renderer — Terminal rendering (human mode) and JSONL output (AI mode)
  • @agentlens/transport — Async queue-based event persistence (console, file, custom)
  • @agentlens/cli — Command-line tools (init, trace, analyze)

Event Flow

Agent Code
    ↓
SDK Call (LLM or Tool)
    ↓
Interceptor (automatic wrapping)
    ↓
Event Builder (construct ARLS event)
    ↓
Privacy Engine (detect & redact PII)
    ↓
Renderer (format for output)
    ↓
Transport (queue & persist)
    ↓
Output (console, file, custom)

Every event follows the ARLS schema (AI-Readable Log Schema), a versioned JSON structure that captures:

  • Event type (AGENT_START, LLM_CALL, TOOL_CALL, ERROR, REASONING_STEP, etc.)
  • Timing information (timestamp, duration)
  • Execution context (run_id, trace_id, step_index, agent phase)
  • Event-specific data (tokens, cost, tool input/output, error details)
  • Privacy metadata (PII detected, redacted fields, redaction mode)
  • Semantic tags and AI debug hints for tool integration

interface ARLSEvent {
  agentlens_version: "1.0"
  schema_type: "AGENT_START" | "LLM_CALL" | "TOOL_CALL" | "ERROR" | ...
  timestamp: string              // ISO 8601
  run_id: string                 // Unique run identifier
  trace_id: string               // Trace identifier for debugging
  step_index: number             // Sequential step number

  agent: {
    name: string
    phase: "PLAN" | "TOOL_CALL" | "OBSERVE" | "REFLECT" | "RESPOND" | "IDLE"
  }

  // Event-specific data
  llm?: LLMCallData              // For LLM calls
  tool?: ToolCallData            // For tool calls
  error?: ErrorData              // For errors
  memory?: MemoryData            // For memory operations

  // Privacy metadata
  privacy: {
    pii_detected: boolean
    redacted_fields: string[]
    redaction_mode: "MASK" | "HASH" | "DROP" | "PLACEHOLDER"
  }

  semantic_tags: string[]        // For searching and filtering
  ai_debug_hint?: string         // For AI tool analysis

// Create instance
const lens = new AgentLens(config: AgentLensConfig)

// Wrap SDK clients for automatic logging
const anthropicClient = lens.wrap(new Anthropic())
const openaiClient = lens.wrap(new OpenAI())

// Wrap any async function as a logged tool
const search = lens.wrapTool('web_search', async (query: string) => {
  return await fetch(`/api/search?q=${query}`).then(r => r.json())
})

// Start a scoped run with full context tracking
const run = lens.startRun({ name: 'MyAgent' })
await run.exec(async () => {
  // All calls here share same run_id and trace_id
})

// Manually log an event
lens.log({
  schemaType: 'REASONING_STEP',
  phase: 'REFLECT',
  metadata: { content: 'The user asked...', reasoning: '...' }
})

// Flush pending events to transport
await lens.flush()

// Flush and close all transports
await lens.close()

CLI Tools

The CLI provides three commands for analyzing logged agent runs:

npx agentlens init

Scaffold AgentLens configuration for your project:

$ npx agentlens init
✓ Detected @anthropic-ai/sdk in package.json
✓ Created agentlens.config.ts

Add these lines to your agent file:
  import { AgentLens } from '@agentlens/core'
  const lens = new AgentLens({ agent: 'MyBot', mode: 'human' })
  const client = lens.wrap(new Anthropic())

npx agentlens trace <run_id> <logfile>

View a specific run in a formatted tree:

  1. TypeScript Strict Mode — All code must pass tsc --strict with zero errors
  2. Zero Required Runtime Dependencies in Core@agentlens/core has no production dependencies
  3. JSDoc on All Public APIs — Every export needs documentation
  4. Tests Before Shipping — 80%+ coverage required
  5. No any Types — Use unknown and narrow it
  6. Async Non-Blocking — Transports use async queues, never synchronous I/O
  7. Privacy First — Redaction runs before every transport write
  8. ARLS Compliance — Every event must conform to the schema

Built With Claude

This entire project was built using Claude Code and the Claude family of models:

  • Claude 3.5 Haiku — Used for rapid prototyping, quick fixes, and repetitive tasks
  • Claude 3.5 Sonnet — Used for most of the implementation, balancing quality and speed
  • Claude 3 Opus — Used for complex architectural decisions and comprehensive implementations

Claude Code's ability to autonomously plan, implement, test, and iterate made it possible to build this complete production-ready library from scratch, including all 8 implementation phases, comprehensive tests, and full documentation.

The development approach leveraged Claude's capabilities for:

  • Planning — Breaking down the project into 8 manageable phases
  • Implementation — Writing type-safe TypeScript code with zero any types
  • Testing — Creating 268 comprehensive tests covering all functionality
  • Documentation — Generating clear, detailed documentation for all components
  • Debugging — Identifying and fixing issues quickly and efficiently
  • Refactoring — Improving code quality while maintaining backward compatibility
